The vehicles, which belonged to staff at Darent Valley Hospital, are understood to have been targeted while they were parked in Darenth Wood Road between 8am and 5.30pm on Monday 11 January 2021.
At present no suspects have been identified however officers from the Dartford Community Safety Unit are conducting enquiries to establish the full circumstances.
Inspector Sarah Rivett, from the Dartford Community Safety Unit, said: ‘Vehicle crime has a big impact on victims, who are left with costly repairs on top of having difficulty getting to work and supporting their families.
‘It is particularly unpleasant that the offenders of this case think nothing of stealing from key workers who are providing exceptional care during a time of unprecedented difficulty and demand.
‘We are reviewing the circumstances and will explore every reasonable line of enquiry. As part of this work, we would like to hear from anyone who has information, no matter how small, that can assist us.
‘Anyone who may have seen something suspicious in the area, or who was driving nearby and believes their dash cameras have caught something suspicious, is asked to call us on 01474 366149 quoting 46/6159/21.
